Practice how to create different data types in C++

C++ Online Editor

#include <iostream>
#include<string> //  included to create string data 
using namespace std; // use std namespace to avoid std:: before cout


int main() {

    char charVariable = 'A'; // Character data
    cout << charVariable << " is a character data" << endl;

    string stringVariable = "Hello World C++ "; // String data
    cout << stringVariable << " is a string data" << endl;

    const char* strVariable = "Hello C like string"; // C like string data
    cout << strVariable << " is a string data" << endl;

    int integerVariable = 10; // Integer data
    cout << integerVariable << " is an integer data" << endl;

    float floatVariable = 3.14; // Float data
    cout << floatVariable << " is a float data" << endl;

    double doubleVariable = 2.71828; // Double data
    cout << doubleVariable << " is a double data" << endl;

    int boolVariable = 1; // Boolean data (0 represents false, non-zero represents true)
    cout << (boolVariable ? "True" : "False") << " is a boolean data" << endl;

    return 0;
